An illustrative embodiment disclosed herein is a non-transitory computer readable medium. In some embodiments, the medium includes instructions for providing a mobile user monitoring solution that, when executed by a processor, cause the processor to capture a first message transmitted over a packet forwarding control protocol (PFCP) interface, extract a permanent ID and a first user plane tunnel endpoint identifier (TEID) from the first message, store the permanent ID and the first user plane TEID in a PFCP protocol data unit (PDU) session record, store the permanent ID in a session details record, capture a second message transmitted over a user plane interface after the first message is transmitted, extract a second user plane TEID from the second message, wherein the second user plane TEID matches the first user plane TEID, and retrieve the session details record using the second user plane TEID.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The medium of claim 1, wherein the session details record include two or more of network information, session information, user information, or a user location, wherein the network information includes one or more of a client internet protocol (IP) address, a service IP address, a service/data network name (DNN), the session information includes one or more of the DNN, a radio access technology (RAT) type, or a quality of service (QoS), the user information includes one or more of a subscriber permanent identifier (SUPI), an international mobile subscriber identity (IMSI), a permanent equipment identifier (PEI), a general public subscription identifier (GPSI), subscriber IP addresses, a mobile subscriber international integrated services digital network (MSISDN) number, or a mobile equipment identity (MEI), and the user location includes a public land mobile network (PLMN).
3. The medium of claim 1, wherein the PFCP interface is one of an N4 interface, an Sxa interface, or an Sxb interface and wherein the user plane interface is one of an N3 interface, an N9 interface, an S1-U interface, or an S5/S8-U interface.
4. The medium of claim 1, wherein the first message is one or more of a PFCP modify request or a PFCP deletion request and the second message is one or more of a PFCP modify response or a PFCP deletion response.
5. The medium of claim 1, wherein the permanent ID is one of an international mobile subscriber identity (IMSI) or a permanent equipment identifier (PEI).
6. The medium of claim 1, wherein each of the UL GTP-U TEID, the DL GTP-U TEID, and the first GTP-U TEID is a GTP-U TEID from an access side of a user plane function (UPF).
7. The medium of claim 1, wherein each of the UL GTP-U TEID, the DL GTP-U TEID, and the first GTP-U TEID is a GTP-U TEID from a core side of a user plane function (UPF).
10. The apparatus of claim 9, wherein the session details record include two or more of network information, session information, user information, or a user location, wherein the network information includes one or more of a client internet protocol (IP) address, a service IP address, a service/data network name (DNN), the session information includes one or more of the DNN, a radio access technology (RAT) type, or a quality of service (QoS), the user information includes one or more of a subscriber permanent identifier (SUPI), an international mobile subscriber identity (IMSI), a permanent equipment identifier (PEI), a general public subscription identifier (GPSI), subscriber IP addresses, a mobile subscriber international integrated services digital network (MSISDN) number, or a mobile equipment identity (MEI), and the user location includes a public land mobile network (PLMN).
11. The apparatus of claim 9, wherein the PFCP interface is one of an N4 interface, an Sxa interface, or an Sxb interface and wherein the user plane interface is one of an N3 interface, an N9 interface, an S1-U interface, or an S5/S8-U interface.
12. The apparatus of claim 9, wherein the first message is one or more of a PFCP modify request or a PFCP deletion request and the second message is one or more of a PFCP modify response or a PFCP deletion response.
13. The apparatus of claim 9, wherein the permanent ID is one of an international mobile subscriber identity (IMSI) or a permanent equipment identifier (PEI).
14. The apparatus of claim 9, wherein each of the UL GTP-U TEID, the DL GTP-U TEID, and the first GTP-U TEID is a GTP-U TEID from an access side of a user plane function (UPF).
15. The apparatus of claim 9, wherein each of the UL GTP-U TEID, the DL GTP-U TEID, and the first GTP-U TEID is a GTP-U TEID from a core side of a user plane function (UPF).
